Toggling between long and short logs for the whole log is not hard.
I can implement this, the we can decide on the UI 

I am not convinced that "toggle detailed info for this entry" is very
useful.  If the detailed info is displayed in a different window, it
should not be too hard either (if the underlying VCS has some easy way to
retrieve such info).

I don't want to see global history when looking at a file , the VCS does
not matter.
